What is an R6 ADS Calculator?

An R6 ADS Calculator (Rainbow Six Siege Aim Down Sights Calculator) is a tool designed to help players convert their ADS sensitivity settings when they change their Field of View (FOV) or aspect ratio in the game. The goal is to maintain a consistent aiming feel, particularly for the 1x scope, across different display and FOV configurations. When you change your FOV or aspect ratio, the effective area your mouse movements cover on screen changes, and thus your perceived sensitivity shifts. This calculator helps you find the new ADS values for Rainbow Six Siege’s “Advanced” ADS sensitivity settings to compensate for these changes.

Players who frequently experiment with different FOV settings or aspect ratios, or those switching between different monitor setups, will find an R6 ADS Calculator invaluable. It allows for a more consistent muscle memory development by ensuring the sensitivity for 1x scopes (and consequently other scopes) feels the same regardless of these changes. Common misconceptions are that sensitivity should scale linearly with FOV or that the in-game “Standard” ADS setting is optimal for all changes; however, the relationship is based on trigonometric functions of the FOV and the game’s specific ADS mechanics.

R6 ADS Calculator Formula and Mathematical Explanation

The core principle of the R6 ADS Calculator is to maintain the same mouse movement distance to rotate a certain angle on-screen, especially when using 1x scopes, after changing FOV or aspect ratio. This is often related to “0% monitor match” or keeping the cm/360° consistent for the base 1x ADS feel.

1. Calculate Actual Horizontal FOV (hFOV): The FOV setting in R6 is vertical FOV (vFOV). We need the horizontal FOV, which changes with the aspect ratio (AR = Width/Height):
hFOV (radians) = 2 * atan((AR_Width / AR_Height) * tan(vFOV * PI / 360))
hFOV (degrees) = hFOV (radians) * 180 / PI
This is done for both old and new settings.

2. Calculate New 1x ADS Value: To maintain the same angular rotation speed feel at the center of the screen (or cm/360 if we were matching hipfire), the new 1x ADS value is adjusted based on the change in the tangent of half the horizontal FOV angles:
New 1x ADS = Old 1x ADS * tan(Old hFOV_rad / 2) / tan(New hFOV_rad / 2)

3. Calculate Other Scope ADS Values (Advanced): Rainbow Six Siege’s “Advanced” ADS settings allow individual values per scope magnification group. These are scaled relative to the 1x value, using the game’s inherent multipliers (0.7 for 1x base in standard, 0.9 for 1.5x, 1.0 for 2.0x etc., relative to a standard 50):
New 1.5x ADS = New 1x ADS * (0.9 / 0.7)
New 2.0x ADS = New 1x ADS * (1.0 / 0.7)
…and so on for 2.5x, 3.0x, 4.0x, 5.0x, and 12.0x, using their respective multipliers (1.05, 1.08, 1.1, 1.12, 1.15) divided by the 1x base multiplier (0.7).

4. Clamping: All calculated ADS values are clamped between 1 and 100, as these are the minimum and maximum values allowed in the game.

Variables Used in R6 ADS Calculation

Variable	Meaning	Unit	Typical Range
Old 1x ADS	Current Advanced ADS value for 1x scopes	1-100	20-60
Old/New vFOV	Vertical Field of View set in-game	Degrees	60-90
Old/New AR	Aspect Ratio (Width/Height)	Ratio	4/3, 16/9, 16/10, etc.
Old/New hFOV	Calculated Horizontal Field of View	Degrees	~73-120
New ADS (X.Xx)	Calculated Advanced ADS value for X.Xx scope	1-100	1-100

Practical Examples (Real-World Use Cases)

Example 1: Switching from 16:9 to 4:3 with FOV adjustment

• Current Settings: 1x ADS=35, FOV=84, Aspect Ratio=16:9
• Desired Settings: FOV=74, Aspect Ratio=4:3
• Old hFOV: ~115.56°
• New hFOV: ~100.39°
• Using the R6 ADS Calculator:
  • New 1x ADS ≈ 46
  • New 1.5x ADS ≈ 59
  • New 2.0x ADS ≈ 66
  • New 2.5x ADS ≈ 69
  • New 3.0x ADS ≈ 71
  • New 4.0x ADS ≈ 72
  • New 5.0x ADS ≈ 74
  • New 12.0x ADS ≈ 75
• Interpretation: To keep the 1x aiming feel similar when switching from 84 FOV at 16:9 to 74 FOV at 4:3, the player should change their Advanced 1x ADS from 35 to 46, and adjust other scopes accordingly.

Example 2: Increasing FOV on the same Aspect Ratio

• Current Settings: 1x ADS=40, FOV=75, Aspect Ratio=16:9
• Desired Settings: FOV=90, Aspect Ratio=16:9
• Old hFOV: ~106.26°
• New hFOV: ~120.97°
• Using the R6 ADS Calculator:
  • New 1x ADS ≈ 34
  • New 1.5x ADS ≈ 44
  • New 2.0x ADS ≈ 49
  • New 2.5x ADS ≈ 51
  • New 3.0x ADS ≈ 53
  • New 4.0x ADS ≈ 54
  • New 5.0x ADS ≈ 55
  • New 12.0x ADS ≈ 56
• Interpretation: When increasing FOV from 75 to 90 at 16:9, the 1x ADS should be lowered from 40 to 34 to maintain the feel, with other scopes adjusted proportionally.

How to Use This R6 ADS Calculator

1. Enter Current Settings: Input your current “Advanced” 1x ADS value, your current in-game FOV, and your current aspect ratio (width and height).
2. Enter New Settings: Input the new FOV and new aspect ratio you want to switch to.
3. Calculate: Click the “Calculate” button or simply change input values. The results will update automatically.
4. Read Results: The “New 1x ADS Value” is the primary result. The table and chart show the recommended “Advanced” ADS values for all scope magnifications to maintain a consistent feel based on your 1x preference.
5. Apply in Game: Go to Rainbow Six Siege’s options, select “Advanced” ADS sensitivity, and enter the calculated values for each scope magnification.
6. Decision-Making: Use these new values to see if the aiming feels consistent with your old setup, particularly for the 1x scope. You might fine-tune slightly based on personal preference, but this gives a very strong starting point.

Key Factors That Affect R6 ADS Calculator Results

• Field of View (FOV): A larger FOV makes targets appear smaller and move faster across the screen, requiring a lower sensitivity value to maintain the same cm/360, but the calculator adjusts to maintain feel, not cm/360 across all zooms.
• Aspect Ratio: Changes how the vFOV translates to hFOV, significantly impacting the feel and the required ADS adjustment.
• Base 1x ADS Preference: The calculator uses your starting 1x ADS as the reference for how you like your sensitivity to feel.
• Scope Magnification: Higher magnification scopes zoom in more, and the game applies different multipliers. The calculator scales these based on the 1x value.
• Monitor Size and Resolution: While not direct inputs, these influence your perceived FOV and how sensitivity feels, although the calculator works based on the game’s internal FOV values.
• Hipfire Sensitivity: The ADS values are multipliers on your base hipfire sensitivity, adjusted for FOV changes during ADS. The calculator focuses on the ADS multipliers themselves.

Frequently Asked Questions (FAQ)

Q: What is the difference between Standard and Advanced ADS in R6?

A: Standard uses one slider that applies pre-set multipliers for each scope group. Advanced allows you to set a specific sensitivity value (1-100) for each scope magnification group (1x, 1.5x, etc.), giving more control. This R6 ADS Calculator is designed for Advanced settings.

Q: Why does my sensitivity feel different after changing FOV?

A: Changing FOV alters the angle of view. A higher FOV means more is visible, but objects in the center are smaller, and mouse movement covers more angular distance, making it feel faster if sensitivity isn’t adjusted.

Q: Should I aim for the same cm/360° for all scopes?

A: Not necessarily. Most players prefer a consistent feel based on monitor distance matching (like 0% vertical match which R6 uses around 50 ADS for 1x) or a scaled sensitivity that feels natural for different zoom levels, rather than pure cm/360 across all magnifications.

Q: Does this calculator work for console?

A: Yes, the FOV and ADS settings work the same way on PC and console, so the calculator is applicable to both, assuming you can set Advanced ADS values.

Q: What if I use a very unusual aspect ratio?

A: The calculator will still work, as it directly uses the width and height you input to calculate the horizontal FOV.

Q: Why are the calculated values for higher zooms so different?

A: Higher zoom scopes magnify the view significantly. To maintain a somewhat consistent feel or monitor match, the sensitivity value needs to be adjusted based on the game’s scaling and the base 1x value. Check out our R6 FOV Calculator for more on FOV.

Q: Is 50 ADS always 1:1?

A: In the past, 83 ADS was closer to 1:1 cm/360 for 1x. With the current system, 50 ADS on Standard or 35 on Advanced (for 1x) corresponds to a 0% vertical monitor match, which is a common reference, but not 1:1 cm/360 with hipfire.

Q: What if the calculated value is above 100 or below 1?

A: The calculator clamps the values between 1 and 100, as these are the game’s limits. If it hits the limit, it means the ideal value is outside the game’s range, so use the clamped value.
